ZitatDTT has officially made its debut in Poland, with services on a single multiplex being offered in a handful of locations including the capital, Warsaw.

The move follows a decision by the Office of Electronic Communications (UKE) to grant the public broadcaster TVP frequencies on the first multiplex (MUX 1) up until the ASO date of July 31, 2013, after which it will have its own multiplex (MUX 3). Telewizja Polsat, TVN, Polskie Media (the operator of TV4) and Telewizja Puls have meanwhile been granted frequencies on MUX 1 until September 29, 2024.

Although TP EmiTel, a wholly owned subsidiary of the incumbent telco TPSA, is initially operating MUX 1, a permanent operator will be chosen by the stations carried on the multiplex within a month.

Separately, a DVB-H service operated by Info-TV-FM has also made its debut in Poland. Initially offering 12 TV channels, it is available in Warsaw and will be rolled out to nine more cities by the end of the year.

ZitatThe likelihood of Poland meeting its current ASO target date of July 31, 2013 appears to be receding.

Rzeczpospolita reports that representatives of the public broadcaster TVP failed to show up at a meeting on digitalisation this Tuesday (November 10), saying they would need until December 8 to consider their situation.

Although Poland’s first DTT multiplex was launched at the end of September, it is still officially operating on a trial basis. Four of the five channels carried by the multiplex – Polsat, TVN, TV4 and TV Puls – have signed an agreement with the operator Emitel, but TVP has failed to do so. What is more, to sign such an agreement it may have to initiate a tender process which could take up to a year to complete.

Comprehensive agreements between the channels and operator are required before the first multiplex can be considered fully operational, although Polsat, TVN, TV4 and TV Puls already consider it to have such a status. However, Emitel needs these agreements before it can start investing in the roll out of the service, which is at present available in only four locations.

One option may be to move TVP’s services onto the second multiplex, a tender for which will soon be launched. They will eventually be carried by a third multiplex.

ZitatThe Polish public broadcaster TVP has opened a tender for the technical operation of what will be the country’s third multiplex. According to Satkurier, the deadline for submissions is December 22, prior to which applicants will have to submit a deposit of PLN 10 million (¤ 2.45 million).

TVP has outlined a four-stage deployment of the multiplex, to which its services will eventually be moved.

ZitatA new plan for the introduction of DTT services in Poland may be adopted at the beginning of 2010.

According to Wirtualne Media, the country’s leading commercial broadcasters Polsat, TVN and TV4 have proposed that the first multiplex, which ostensibly made its debut at the end of September, should be allocated solely to the publicly owned TVP, while they should be placed on the second multiplex.

The plan is understood to have the support of both the Office of Electronic Communications (UKE) and National Broadcasting Council (KRRiT). A meeting to discuss it is scheduled to take place on December 21.

DVB-T in Poland (latest news)

As inform UKE (UKE is "polish BnetzA") and Forum on Emitel (operator) website from 27.09.2010 to 01.10.2010 experimental (all DVB-T in Poland are "experimental" since... 2003) emisions od DVB-T signals may be distorted or temporary switched-off.
Last part of UKE anouncment:

"As unofficial inform TP Emitel, emmision TVP programs in DVB-T in MUX1in Lubuskie (Żagań-Wichów and Zielona Góra-Jemiołów will be NOT CONTINUED "for now".
TVP1 programs in Poznań and Warszawa will be continiued as long as all TVP progrrams will be moved to MUX3 (own TVP MUX).
President of UKE will be observe the situation of TVP progams in DVB-T and situation of MUX1 and MUX2 (existing private stations) after 30 of September 2010 and due to results make decision for next steps. President of UKE will be inform about his deciosions".
Sorry for my poor english but I want inform You about planned switch off MUX1 near German border on channel E45.
Best regards.

So MUX2 started commercial from today in Wichów, Jemiołów, Poznań, Raszyn and Warszawa.
In second step MUX2 must starts before 31.12.2010 in few next localisation.
In this step will be Kołowo on E34 and propably Swinoujście in SFN on the same channel.

TVP MUX3 must starts in Kołowo on E49 before 27.10.2010 so i thing, private stations in MUX2 will be tried to run in the same day in Kołowo or... 27 but December 2010 (just after the Cristmass).
Polsat and TVN having own pay-tv sat platforms.
They want make maximum money BEFORE Cristmass, when people buys new TV-sets.
They want have last big deal Cristmass and maybe plannned good offer and good films from 24 to 27 December.
When step2 of MUX2 runs, on Sylvester and New Year, they give only remakes and borring programs.

ZitatThe Polish public broadcaster TVP is pushing ahead with its digitisation plans despite all the upheavals caused by yet another change in senior management at the station. Rzeczpospolita reports that the first TVP channels on the country’s third multiplex, which has been allocated exclusively to the station, will appear on October 27 this year.

The third multiplex is operated by Emitel and will cover four voivodships, thereby reaching at least 58% of the population. It should achieve complete national coverage by May 2014.

TVP’s new management also have to address the issue of TVP’s agreement with SES Astra, which was extended by a previous president (Piotr Farfal) a year ago. The agreement has caused controversy in some quarters and negotiations between the two parties are ongoing. At this stage it is understood that TVP has no plans to resurrect its ill-fated DTH platform project.

9. September: Polnisches DVB-T vor dem Durchbruch (MUX2)

ZitatFollowing months of frustrating delays, Poland is finally on the brink of launching a full DTT operation.
The country’s four leading commercial broadcasters – Polsat, TVN, TV Puls and TV4 – have finally agreed on the terms of an agreement with the national transmission company Emitel that will see the latter become the operator of the country’s second DTT multiplex (MUX2).

If the agreement is signed before the end of this month, Emitel believes it will quickly be able to launch the second multiplex, which will carry a total of eight channels, two each from the four broadcasters. In practice, MUX2 could be operating from September 30 in four locations, including Warsaw, where Emitel is already undertaking DTT trials.

Earlier this week it was reported that Emitel will begin operating Poland’s third DTT multiplex, allocated solely to publicly owned TVP, in late October.

14. September: Polnisches DVB-T eine Kostenfalle (MUX2)

ZitatThe cost of launching and then operating a channel for the first year on Poland’s commercial DTT multiplex could exceed PLN 20 million (¤ 5.1 million). However, according to Rzeczpospolita, such a high amount would only be paid by new rather than existing services.

The second multiplex, which is expected to make its debut at the end of this month but is unlikely to have significant reach before the middle of 2011, will carry Polsat, TVN, TV Puls and TV4, along with one additional channel from each of the four. The latter will include TV7, which is a satellite channel and for which TVN will have to secure terrestrial rights for its content.

There are also concerns that the money invested by broadcasters in DTT is unlikely to be recouped quickly in a market in which cable and DTH services are already so popular.

ZitatThe Polish National Broadcasting Council (KRRiT) has launched a consultation into the allocation of spare capacity on the country’s DTT multiplex. According to Satkurier, quoting the regulator, the filling of this capacity with new TV channels is key to the creation of open and pluralistic digital terrestrial TV in Poland.

At present, the only channels on the first multiplex are TVP1, TVP2 and TVP Info, with the public broadcaster’s other services having been reserved capacity on what will be the third multiplex. There is additional capacity for four more SD channels on the first multiplex.

ZitatThe launch of a full DTT service has moved closer in Poland, with the transmission company Emitel signing agreements with the commercial broadcasters TVN and TV Puls. According to Parkiet, the two remaining broadcasters – Polsat and TV4 – which have also had capacity allocated on the second multiplex are likely to reach similar agreements with Emitel shortly, in the case of Polsat either today (September 29) or tomorrow.

This all points to the launch of the second multiplex, which has hitherto been operating on a test basis in five locations including the capital, Warsaw, this October.

The agreements with the four broadcasters, each of which will distribute two channels on the second multiplex, is likely to prove quite lucrative financially for Emitel. It is likely to earn around PLN500 million (¤125.9 million) from them over a 10-year period.

30. September: Polnisches DVB-T offiziell gestartet (MUX2)

ZitatFollowing of months of delays, digital terrestrial broadcasting will finally make its debut today (September 30) in Poland. This follows the signing of agreements between the national transmission company Emitel and national commercial broadcasters Polsat and TV4 yesterday and TVN and TV Puls earlier this week.

The four broadcasters will each contribute two channels to the second multiplex, which, according to a statement from Emitel, will be launched from transmitters in Warsaw, Poznan, Zielona Góra and Zagan today.

Emitel says that the negotiations between the parties were helped by the fact that they had already reached an understanding as far back as June last year. Commenting on the launch, Emitel’s president Przemyslaw Kurczewski said: “two multiplexes with 15 digital terrestrial channels is finally a fact”.

The first multiplex is currently carrying TVP channels, although the thematic ones will migrate to the third multiplex, which will launch on October 26 and be allocated solely to the public broadcaster.

Poland’s DTT service will eventually offer viewers around 30 channels.

Yes. This afternoon starts MUX3 from Kołowo on E49 (how about TV AL ? Few days ago I received via tropo analog TV AL).
Problem is from strong analog signal on E48 (Polsat 600 kW ERP).
MUX3 in Kołowo on E49 only 10 kW ERP.
I live here , exactly 70km on north from Kołowo.
I have small house on Żółwino village (population 20 persons), but i have instalation with antenna plug in each room.
I have two antennas: Yagi-Polaris (max gain to buy in Poland on V band. but covered IV band also) and 9-elements Yagi on VHF-III.
Two coaxial cables going down to "building amplifier" (like in cable TV in buildings)
I have no receive DVB-T on E49 with aplifier on Sony KDL52-W4210 and STB RWT (polish production STB) DTV-401 (HD with MPEG-4).
If I connect Yagi-Polaris directly to TV Sony i also have no receive but TV long searching on E49.
But polish STB conected directly to antenna received... corectly.
I have intermodulation problem in amplifier from strong E48.
And HF unit in Sony is not very good (not receive directly with antenna but polish STB receive corectly).
Today Emitel emits only TVP1 and TVP2 from Kołowo, Gdańsk Chwaszczyno, Iława-Kisielice and Plock-Rachocin.
Commercial start 27.10.2010.
TVP in MUX3 planned: TVP1, TVP2, TVP Info (regional versions), TVP Historia (History) and TVP Kultura (Culture).
Will be not TVP Sport and TVP HD because "this programs are premium programs...".
In Lubuskie (Wichów and Jemiołów) will be not... TVP in DVB-T at all for now...
I hear rumours that commercial (private stations) MUX2 start test about 15 of November on E34 100kW from Kołowo with: TVN, Polsat, Puls, TV4 and maybe TVN7 and Polsat Sport-news).
TV Puls waiting for terrestial concesion on TV Puls 2 and TV4 waits on concesion for TV6.
About 15:00 CET all test MUX3 transmisions was switched off, but as oficials says, starts for few days with new content.
Now on E49 is not DVB-T signal.

Main antenna system is hi-gain DIRECTIONAL (main direct - polish territory)
As EU agreement, since 2009 all EU countries TV and FM broadcast station need not have rejection to either EU country, so Poland in Kołowo need not reject signal to the west and north.
But for the technical and economical reasons, TP Emitel uses old TV antenna system _WITH_ rejection to other country direct.
So main antenna systems on UHF on all station near borders have rejection and directional horisontal characteristic.
Curiosity all TV station on UHF band (IV and V band) in Poland uses H polarisation although errors in documentation (mess is not only but also polish specialty).
In VHF-III some station uses V polarisation, but most uses H polarisation.
VHF-I and VHF-II as You know is not in use for TV broadcasting in Poland since 1995. OIRT FM is not in use since 2000 but some stations has temporary permisions to 2004 like Radio Koszalin from Piła-Rusinowo operates on 72,8 MHz to 2004 and RDC from Łosice-Chotycze (near Belarusian border) on 68,03 MHz.
This station has not free frequency on this objects to 2004.
Remeber, that not every channels on CCIR can run when OIRT receivers is in use, because mirror signals is occur (for example: on simply OIRT receiver tuned on 70 MHz, I can receive strong signal from 91,4 MHz (plus 21,4 MHz - two times intermediate frequency of receiver).
Today some people in Miedzyzdroje (fmr. Bad Misdroy near Swunemunde) using old OIRT receivers and have not idea, that is OIRT band - they receive 87,5-95,4 MHz.
For exaple my neighbor still use OIRT receiver and listen Radio ZET from Świnoujście transmited on 91,8 (tuned his receiver on 70,4 MHz) in stereo (in Poland was Zenith stereo MPX signal on OIRT like on CCIR in all the World).
In Russia and fmr. USSR republics was (and still is) russian "planar stereo system".
Some countries like Ukraine and Belarus runs CCIR station like in Poland in 90-tees: in common object twin transmitters OIRT and CCIR with common stereo coder MPX even with RDS on OIRT.
Polish stations in Warsaw (when i live to 2001) transmitts "unwittingly" RDS on CCIR and in OIRT
Some receivers produced for polish market (Philips, Sony etc) has OIRT and CCIR band (even expensive car radios with RDS and home stereo systems) on PLL and digital display.
This receivers tuned 65,5-74 and 87,5-108 MHz (on OIRT with step 0,03 MHz and n CCIR with 0,1 MHz).
Some receivers has continuous 65,5-108 MHz or subbands 65,5-74 and 76-108 MHz (japanese and european/USA band).
My Sanyo receiver has 65,5-108 MHz. I can receive (to 1995) audio TV from channels R2, R3, R4 and R5 (R4 was not in use in Poland except few mountain low power repeaters).
TVP1 on R2 ransmits in Warsaw and Piła-Rusinowo on 65,75 MHz audio.
TVP1 on R3 with 83,75 MHz audio was in Zielona Góra Jemiołów (now on E32) and from Święty Krzyż Peak (the best localisation to broadcast in Poland - near Kielce on 612 m above sea level (and 400m above rest of terrain). Now TVP1 on E38 (TVP2 on E28 with 1000 kW erp).
R5 was only one transmitter - TVP1 from Suwałki-Krzemieniucha (north-east corner of Poland near Lithuanian border).
TVP1 on R5 was excelent signal in Vilnius.
Now on E53.
TVP1 from Suwałki i received during tropo in Warsaw on 99,75 MHz (audio ; video carrier as "brumed" carrier i received on 93,25 MHz).
In my receiver i have no R1 audio (56,25 MHz)
But was only one transmitter TVP1 in Trzeciewiec near Bydgoszcz and Toruń (Thorn).
In E-sporadic seasons, italian channel A RAI-Uno was moves across the screen (other raster, so video sideband was visibly like contours with logo with no or weak moire effect).
In 1987 in headline news in TVP1 informs about "problem with receive TV signals on Kujawy region" caused "strong solar activity" and with interviev "solar physics faculty" profesor from Torun Nicolaus Copernicus Univerisity.
In Warsaw I very often receive NRK1 in E-sporadic season.
I lived in 80-tees in Piaseczno - 20 km on south from Warsaw.
On the roof we has two Yagi antennas: on R2 (TVP1) and R11 (in 80-ties TVP2) directed to north.
In Warsaw thee was no UHF TV.
On R2 it was 3-elements Yagi antenna and on R11 it was 5-elements.
I tuned my TV and I receive test card "named" NORGE NRK1.
During tropo i receive very often Ukraine, Belarus and central USR program.
I receive in Warsaw on room antenna with amplifier (bought in West Berlin in KaDeWe in 1986) DFF1 and DFF2.
DFF sometimes was very strong in Warsaw even on room antenna.
We hunt with my family on ARD or ZDF from West Berlin.
In that times Poles needed special permision from PIR (like BnetzA but in comunistic Poland) to buy and second to mount a satelite receiver.
In Piaseczno ( 35 000 peoples town) only one person has in 1986 satelite receiver and a few has video recorder - we has german Saba VCR with camera "retuned" audio in tuner to 6,5 MHz and in RF modulator to 6,5 MHz out Sony KV-1820 has not SCART or chimch video input. It hans't even a telecommander (TV). First telecommander we has in Saba VCR.
This VCR without problems record and play MESECAM TV signal.
First PAL station in Warsaw was pirate Top Canal TV (i call that pirate "instititution pirate" - a big and rich new corporation runs after communism colapse or even during collapse).
They both TV transmitter in west Europa, so its work on E57 woth audio 5,5 MHz.
50 km from Warsaw was TVP2 small transmitter in Bartniki.
TopCanal transmit all time (much VHS cassete films from local cassete rent agency).
About 14:00 afternoon starts TVP2 so Emitel (in those times state owned ZRIT) runs transmitters at 13:30.
That was old ZARAT (non-exist today) polish factory produces TV and FM transmittres (like Warel produces only FM transmittres OIRT and CCIR but Warel produce even CCIR FM transmittesr in 80-ties to DDR).
So if VXCO starts on Top Canal moire effect was apear in first minutes "swimming" up to down or down tu up slower and slower to stabilise of frequency.
In 1991 You may do evrything in radio bands in Wasaw.
You can transmit where You want and every You want.
Poor develop telephone network. One of 100 tries to connect t other part of city was succesfull - for example if You want to call from Żoliborz to Mokotów - numbers starts from 4 - You hear busy signal after dial only first digit 4. So tray next time and next. Some days i must dial up 100 times when after 4 was silence and I can try to dial second digit for example 9.
And pry to was no busy after 49 (very often) or pry tu subscriber was free and ... was in home...
So with no cellular network, citizens buy illegal Jetphone (hi power cordless telphone operates on 84 and 227 MHz).
Jet Phone made n Hong-Kong was 30W power and was ideal to mount in car or in other apartmen (for example to "give telephone" own family, aunt, uncle, granmother etc).
If one person have telephone in family, they share line to other.
Intercom function allowed to make conetion with family and when family want make normal call, use public line from my home.
In next times peoples can buy scramblers because 84 MHz was often receive on normal FM recivers (for example with continous 65,5-108 MHz band).
If You want give tephone to Your family - antennas was non suspicious appear.
Yagi on 227 MHz (R12) and 84 MHz (R4) one above other appears especially in Warsaw as normal TV antennas (TVP1 on R2 and TVP2 on R11).
Only direcion sometimes tell taht is pirate instalation.
But PAR (next of comunistic PIR and ancestor of present UKE) not interest bands exept air bands (air traffic safety !).
PAR was not interest broadcast band, PMR/PAMR bands amateur or other in those times.

"TVP1 on R3 with 83,75 MHz audio was in Zielona Góra Jemiołów (now on E32) and from..."

I heard a signal from Poland past 1990 in my Sony receiver on a frq < 84 MHz. Didn't know from where it came. Now I have my solution of an on riddle. The transmitter place of Jemiolów was my supposition. I am situated ~ 110 km SW of Jemiolów.

"Please remember confusion with Radio Puls from Stok Izerski, allegedly illegal operate on Osterwelle FM channels.
As it turned out, polish station operates with knowledge and agreement of BnetzA."

In good neighbourship people should maintain a loving contact with each other. As far as I know the Elsterwelle in Hoyerswerda (102.8) is dissatisfied with the situation and Radio Plus is using his Tx legal. This situation - two adjacent Tx on same frq - could be relaxed with changing of polarisation at one of this towers. What do you think?

"TVP1 on R2 transmits in Warsaw and Piła-Rusinowo on 65,75 MHz audio. "

Are this audio channels still on air? When I was in Kamien Pom. (ZP) and in Tuchola (KP) last year I couldn't receive any station on 65.75 FM.

Greetings / Dosiego roku!

Hi Ingo !
You are right.
Two adjacent transmitters shoud use orthogonal polarisation, but station must use parameters as given in premision from UKE (and UKE coordinates with BnetzA).
If UKE and BnetzA make mistake - stations must transmit according given parameters.

When i lived in Warsaw i has a very good point to receive far stations.Fort Bielany in Bielański Forest.
50m from Weischel (Wistula River - Wisła) but on beautiful Warsaw Escarpment (Wisła is the biggest "irregular" european river - wild even in city area.
Las Bielański (see previous sattelite picture and use zoom out above "Zbliż" button) is unparalleled in Europe (in present days) natural form.
And nobody watches.
Altough no police patrols its very safe place after sunset.
I walk alone in summer evenings.
With many radios of course.
In 1997 I stars a pirate Radio Kaskada on 70,31 MHz (OIRT piracy...) later moved on 71,0 MHz.
So after end of program maked with my friends (23:00CET) we often go or ride to Las Bielański with receivers (OIRT FM).
In 1998 we starts local pirate TV station on R2.
R2 was purposeful, because many paoples and AIZ instalations (Antenowa Instalacja Zbiorcza - Common antenna instalations in multifamily buildings) have antenna and amplifier insert module on R2.
On some city areas _A_FEW_YEARS_ after TVP1 R2 switch off, local AIZ was not modernised, so peoples can recive only TVP1 on R11. Purposeful was transmitt on R2 when it was clear.
Later I use R7 (on Wolin Island) in H directional and later V omnidirectional polarisation.
TV4 form Szczecin downtown is not coliding, because they use a very low power (i don't belive documents and 500W.
500W - yes, but before 2006.
In 2006 on Szczecin Dąbie Rail Station on my radioscaner Icom IC-R2 i receive very weak TV4 audio on 189.750 MHz.
10W not more...
So since 2006 i have clear R7 channel.
Higher is difficult to build (from sratch - i buld only what i myself designe - for prototype to working transmitter) especially for expensive power transistors (i use russian KT925A, KT920A. KT920b and KT-920B).
It cost 18 PLN (about 5 Euro).
KT920B works on conditions: 13,8 V Uce, up to 175 MHz (in documentation - higher works series 925 up to 300 Mz), max RF power out for transistors ending by "B" leter (cyrylic) is 15W in 13,8V Uce 920 and 925 series and 20W in 24V Uce 922 series.
So as russian product - eatch piece have little other parameters.
Iis often found in "B" series.
One piece cause errors in silcon dopant makes half frequency "parastic" signals (total close of P-N chanel only every other period of signal).
Other piece from box (i always buy few pieces even if i need only one) may work properly in this some place in circuit.
BLY trasitsors are to expensive for me (but I have one just in TV R7 VHF-III transmiter).
MRF transistosrs i can only watch in internet.
So in 90-tees in Warsaw me and my friends makes much piracy activity i north-west part of the city (other groups works in other part of he city).
We transmitt:
- OIRT
- CCIR
- TV analog
- DRM test on high HF bands
- HF AM pirate station
- MW AN pirate station
- RRL (PMR/PAMR) pirate activity (radio links to family and friends)
- Pirate use of former RASZ network on 150/154 MHz (former Polish Railway gates "like BTS" connects fix separated from public network telephone system to selected FM semiduplex channels).
RASZ was not in use at last but still "on air".
If You have TRX with special (polish modify of CCITT ZVEI tone) signalling, You may conect to other FM TRX in Poland, Chech, Slovakia and ever DDR (only to fix DDR Railway telephone network).
Dialng for example from Warszawa-Zachodnia radio gate to Swinoujście:
~979~873~772~0000
979 - former direct code in PKP network to Szczecin
873 - former direct code to Świnoujscie
772 - "subscriber" number in Śwnoujście PKP network - to radio gate
0000 - opened gate like "CQ call" (0000 or number of train f.e. 8310 but after 8310 gate emits 8310 and waiting for 830 response).
In Świnoujscie Przytór was RASZ gate on 154,400 MHz out (some 150,xxx but i not remember in channel). Pirates never use trail traffic channels to avoid a risk in railway. Poish pirates is very responsible. So autorities low interests of them.
Other piracy network was progenitor of cellular network - RTP 162/167 MHz.
Some chanels was "for service use only" channels and free of charge (we never call on someone subscriber number bill - we was not a thieves).
RTP in Grzywacz Hill 900m from sea but 100m obove sea level, was on 168,400 MHz.
We makes tries to use maritime public telephne service.
In Szczecin area code +48 91.... was public acces number 908.
After dial 908 (for example from publc phones) You can reach operator in Szczecin Radio (now public acces is canceled and is no Szezczin or Gdynia Radio - now is only one - Witowo Radio).
From Grzywacz on maritime channel 26 and 27 (meteo anouncments and navigation alerts on 161,900 MHz).

To be not quite off-topic :-)
I still receive German serices like Grentzschutz (sory if mistake in name) on mid-band (74-87,5 MHz).
Rare on 172 MHz and no on UHF.
But every band German serices not use CTCSS subtone squelch.
During summer E-soradic i see open all German repeaters with noise from sideband of R3 channel.
So users be nervous for that ("verfluchte...")
I tune on 83,75 MHz in WFM and hear for example BT1 (Belaruskoje Televidenye 1) on signal S9+.
After 2003 all serices in Poland must use channel step 12,5 kHz (before 25 kHz, according to German services 10 and 20 kHz channel step) and must use CTCSS subtone (not aplicable on maritime VHF and NMT-450 MHz still on air in Poland.
NMT You can hear from Grzywacz and many other localisation.
Since summer 2010 NMT has not mobile subscribers but Polish Telecom (Telekomunikacja Polska) in agreement in Centertel (TP is owner of Centertel -> all owned by France Telecom so GSM centertel network was renamed to Orange) using analogue NMT network on 450 MHz to deliver fix telephone (polish law obligation and financial alimentation from the State).
In Poland, every resident have a priviledge to have a fix telephone.
TP must sin a contract in 30 days with every want and in this agreemet - determine a day of connect to public fix network - max: 6 monh even if You live in center of Wilderness or on Rysy Peak in Tatra Mountains.
If TP not does not meet this condition _MUST_PAY_You_ EVERY MONTH eqivalent of monthly subscription pay tariff (they must pay You) chosen in contract.
So if You anticipate to TP don't misses termin - chose in contract most expensive tariff plan.
If TP connect You, You may change a tariff plan for the cheapest.
My Neighbour having summer house in my village and live in Berlin for my advice sign a contract and for a reason of internal circular letter in TP (i was work in TP) from 2009 was withheld conect new subscribers.
For "big cost" (not applicable to bussines subscribers) reason.
TP prefer pay a monthly compensation to unrealized subscriber then connect a line.
I'm not surprised, because France (France buys Polish Telecom) is oasis of socialism and no does not pay for them, especially here in Poland.
Backing to radio.
Polish pirates in present time using illegal trunking comercial networks to talk country-wide area and sometimes to make conections to public telephone network.
One of network "present" everywhere in Poland is DIGICOM7 network operates 416,5-41,5 & 426,5-428,5 MHz uses by energetics companies.
So, many pirates programing his trunked adio on free numbers and program his radios on lowest priority call to make no risk in legal users.
This MPT-1327 trunked system disconect pirate call when crush is apear in network.
From Grzywacz control channel 428,9375 MHz and two vice chanels: 428,0375 MHz and 428,150 MHz acive aspecially during strong winds or heavy snow (like now).
Two days ago i have not a power in my village, ant three days ago too.
But some vilages like Ładzin, Kodrąbek or Kodrąb Kolonia waqs not power DURIN three days (i hasn't only few hours).
At the end a curiosity.
Each subscriber of polish Telecom have dial-up acces to Intenet dialing 202122 ad use user: ppp password: ppp
Not rachevable from abroad.
But this achevable from Germany:
+48 25 781 7777
user: sokol
password: sokol
This is small operator in east Poland and this number is open and legal acces from everyone.
Let's try if You have dial-up modem on PSTN or ISDN.
By the way: in Germany most of lines is ISDN.
In Poland 100% exchanges are digital but most lines is PSTN.
Even ADSL Internet acces is mosly on Annex A (for PSTN - not ISDN Annex B).
ISDN in Poland is not popular.
Even public phones is on PSTN (but perfectly preserve from phreakers on polish solutons).
I was a phreaker, so i develop many methods and many solutions.
Italian Urmet factory told, that in no either counrty "are not problems but Plish Telecom still request for new security solution.
Even in Russia or USA their standard systems are sfficient.
Sometmes i go for shoping to Ahlbeck and I see only ISDN public phones (on coins and cards) connected to EWSD Siemens exchange (i recognize by audio signals).
On this side of border in 91 Szczecin area we have 99% 5ESS Lucent Tecnologies exchanges
In Warsaw 95% is Alcatel S-12J
In Gdańsk works polish fully digital DGT exchange (for example DGT-3450).
DGT exchanges is in use in "sensivity" sectors like Ministry of Defense or Mnistry Of Internal Affairs.
For simply reason : this is polish construction (very good technical level like Siemens od Lucent and beter than Alcatel) have no back doors... :-)
At the end some test numbers:
Alcatel S-12J: +48 22 639 70 99
EWSD Siemens: +48 22 812 07 99
5ESS Lucent: +48 22 834 02 99
all legal to publicity numbers.
In 90-ties was a test numer with music on ACMM (Automatyczna Centrala Między-Miastowa).
In those times ACMM (long distance and international eschange in Warsaw on Św. Barbary street) realized on Pentaconta PC - CGI.
Now on EWSD Siemens.
I works on Koło PC-1000C local exchange in 90-tees (west - north west region of city).
All analogue exchanges was replaced out in 2007.
Poles makes CID, DTMF and even DTMF-CLIP system for Russian on Olimpic games in 1980 in Moscow.
Few big factories was sell out afrer 1989.
On my exchange i have polish PCM digital tracts produced in 1985 (by ZWUT Teletra).

As inform TP Emitel, yesterday (01.01.2011) the last test and last MPEG-2 DVB-T transmitter was switched off.
It was test TVP transmitter in RTCN Sucha Góra near Rzeszów.
UKE willingly would allocate the new destination of E42 channel from this localisation, but noone has apply for the radiocommunication premision.
In my opinion, in TVP govern parasites.
It coul'dnt be an accident, because it's so much such "accidents", operates for the benefit private TV stations.
So, another cause for prosecutor or NIK (Najwyższa Izba Kontroli - Supreme Chamber of Control).
In Poland, "Detriment To The Company" is a crime.
Few Years ago, TVP signed a contract with SES Astra for big money to create own DTH platform.
The Platform worked only two weeks (peoples alredy prchased expensive DVB-S2 tuners and mounted "squint" converters. Major of citizens use only Hot Bird directed satelite antenas due to all existing DTH transmit from HB and almost no FTA polish programs on TV-SAT, excluding "such interesting" programs like "teleshopping" or other (Tele5 or similar programs nobody watch).
As writes users on Forum Emitela and especially here, Cable TV Networks in Jasło, big TVK company (Vectra) in Krosno have no TVP1, TVP2 and TVP Info, because they takes this three major programs... from E42 DVB-T MPEG-2 test emission (test lasted abt 5 Years ).
It gets worse
Few mountain repeaters also taken signals from experimental DVB-T from Sucha Góra.
Now channel E42 and eqipment are wasted.
Peoples are mad !
In their TVK disappeared TVP1, TVP2 and TVP Info.
And no chance to back TVP Info in local version, because this is not available abt few kilometers from Rzeszów City (TVP Info Rrzeszó have only one analogue transmitter - on E40 in Rzeszów Baranówka with 1 kW ERP !
So, coverage is abt. few kilometers. I thing - even not all City...
And Podkarpackie Voivodship is very large.
During summer 2010 TVP and Emitel also tried to switch-off E42, but flood was occur and authorities apply to TVP and Emitel to switch on (few days was not a signal) this emission due to "important social interest".
From yesterday, Podkarpackie and mountain repeaters has no TVP1, TVP2 and TVP Info.
TP Emitel switch over his repeaters to analogue receive TVP1 on R12 and TVP2 on E29 or from satelite receivers.
TVK companies probably few days will determine "what happened" and seek a solution.
TVP1 and TVP2 they can reach from analogue terestrial sinal from Sucha Góra, but there is no TVP Info in Rzeszów version on satelitte.
"Houston, we have a problem..."

Oh.. who coordinates ?
Nobody !
Nobody rules in Poland.
O'pardon.
Neighbours ruling.
But exception was occur.
For example: Since nineties BnetzA try to change TVP1 from Kołowo R12 to UHF (BnetzA offered German GE channel on UHF).
Request was refused.
In this case, rightly, I thing.
VHF-III is still needed in Zachodniopomorskie.
ON UHF all neighbour countries coordinates all channels and Poland was agree on everything.
Especially on CCIR FM band in southern parts of country.
So, its difficult to coordinate something.
UKE try to issue a radiocommunication premisions for Emitel with V polarisation in adjacent object.
So... Emitel ignored documants and runs new DVB-T with H polarisation, because they HAVE only H antennas on UHF.
And...rightly !
Don't remake mistake like in other countries.
Preserve only H polarisation on UHF in Poland.
I lost weak signal of Polsat form Świnoujście in Żółwino, where I live (now i am in Warsaw).
But previously i was strong interference on TVN from Białogard (E32) from Jemiołów (TVP1)
Fortunatly, I received TVN from Kołowo and TVP1 from Kołowo on VHF-III (very strong ald clear).
Only DXers could have problems.
DVB-T form Toporzyk was delayed to ASO.
Polsat from Świnoujście and DVB-T in Białogard its not a problem.
Really problem is in central Poland.
MUX-2 from Rachocin with 100 kW ERP and analogue TVP1 in Ciechanów with 1 kW ERP (only 65 km !!!).
Nobody in Ciechanów can not receive DVB-T MUX-2 and nobody can receive local analogue TVP1 without interferences.
For a long time Emitel plans to change TVP1 channel in Ciechanów, but TVP is not interesting to pay for that.
It seems like TVP trying to "overdrive" all small old object. Like squeeze lemon.
Use long as posssible, but not invest.
And then switch off.

EDIT:

I'am in Warsaw now.
On channel 7B there is DAB+ test MUX contains T-DMB video signal form Polskie Radio 4 "Radio Na Wizji" Intenet stream.
I test DAB+ 13 stations on my USB Not Only TV tuner with D.Radio aplication.
I wait for Iriver B20 to test T-DMB contain.
At all 14 stations in one MUX.

ZitatSeltener BesucherYou know whether you are rich or poor is an inner state. From the perspective of Poland probably a lot of German are rich. The Germans always look for someone who is much richer and they always find someone. You can always look for reasons to be unhappy. It is our education and culture that limit us. This is overcome.

I agree.

This has nothing to do with the market. We are a big market for you. Would EU exclude Poland, would explode unemployment in your country. We would let in the Balkans in the EU and sell our products there. Maybe not for food, Germany is the master of the export and supplies in the world. Please do not write nonsense.

I disagree.
Excluding Poland, You close the biggest east Europe market.
Excluding Poland from EU, You let to restore import payment, open the door to renacionality of T-Mobile for example.

DVB-H in Warsaw operates on E37 SFN from few localisations with about 3,2 kW ERP each transmitter.
Not all stations are on air in the city now.

Hello Nohab !
Polish wholesale operator chosen in a tender is INFO-TV-FM operator.
This company won with a biggest mobile phone operators trust.
So, the biggest mobile operators won't buy a service (unofficial pact) in INFO-TV-FM.
They play to bankrupt the IFO-TV-FM and they count on next tender which they win.
So, INFO-TV-FM transmitt a FTA service with many programs which they obliged in tender license.
Operators making all in they power to no be available phones which can receive polish DVB-H.
Nokia N96 and few other phones (also other producers) were withdrawn from the shops.
Even in Nokia polish head shop, You can't buy any equipment to receive DVB-H.
Only private import from other countries allows buy a receiver.
But not everyone working abroad receiver, works properly in Poland.
My two friends have two N96 phones.
One received polish DVB-H properly and either receive only radio content.
And even the same firmware... like.
Polish operators have "long hands" and they play to bankrupt INFO-TV-FM (broadcast FM and TV operator).
Its difficult to buy working properly in DVB-H phone, but people are resourcefull and buys a receivers.
So, INFO-TV-FM transmitt FTA many stations, even available only in pay-tv (DTH or cable TV).

T-DMB in Warsaw on YouTube.
Receiving condisions:
Inside city bus, Polish Solaris Urbino 18, here.
Its 4,321km from transmitter antenna.
DAB+ with 12 stations, including content T-DMB with 1 TV station ("Radio na Wizji") Polskie Radio 4 (Czwórka) is transmitted from PKiN with 2 kW erp power in H polarisation, omnidirectional.
In Radzymin (*), 22km from transmitter, receive appears, aproaching to Warsaw, but must outdoor.
In compare with FM PR 2 CCIR analogue signal from the same object with 2,5 kW erp, FM have better coverage (even in Strachówka.
* - In Radzymin in 1920 polish army commanded vy Marchall Józef Piłsudski stoped 6,5 times bigger Red Army.
Piłsudski rescued Europe from comunistic revolution (so we have European Commmonwealth instead Sojuz Soviet'skih Evropejskih Respublik).In Deutsch
In weak signal area, receiver needs long time good signal (not work in move due to cyclic drop out of signal - mobile effect).
Like short wave DRM, need long time good signal to catch sychronise.
So behind city area, You may receive signal but not in move.
Resolution on Iriver B20 is very good, but there is a deinterleave problem by operator side (visible on film of fast motion - horisontal strip lines).
Move on the screen it's not fluent but I don't know is it repairable in T-DMB for example enhanced a bandwith to DMB content.
Strip lines are repairable and I proposed to Emitel to do this.
Colour Moire effect is only on film due to camera refresh.
Fluency of motion on the screen is sufficient to Youth music.
Litle strobe effect seems be purposeful and normal during music videoclips.
But other scenes, like live studio broadcast is unnatural.
So, other content except music videoclips will be looks unnatural.
Signal in the city is good and withouts drop-outs.
Also its insensitive to industrial interference.
But out of city area, signal is crearly weaker then FM with the same power and from the same localisation.
Moving during receive causes mobile effect on FM and completly fade out of DAB+/DMB signal.
Only signal level indicator varies from zero to full signal.

And news about Polish DVB-H.
From TP Emitel Forum topic.
User eMTi writes to INFO-TV-FM about switch off DVB-H network except Warsaw on E37 (still on air).
INFO answers (Google translate):
"Dear Sir,
Thank you for your interest in our company and contact.
InfoTVFM accordance with the decision of UKE provides mobile TV service (currently DVB-H) as a provider of infrastructure and content in the wholesale model. This means that the final shape of the offer will have the effect of direct partners such as the composition operators, satellite and other entities.
Mobile-TV service available at this time for end customers (buyers) is not a business, general public, and is limited territorially.
Currently, in all towns outside Warsaw broadcast signal is temporarily suspended until further notice â. Work is operational and we are not able to determine the moment of resumption of service.
An important point to emphasize is the pre-commercial nature of the service, which means that access to mobile TV is free. The situation changed when the acquisition by InfoTVFM retail partner or change in strategy and in this situation will encode the signals, and reception of mobile TV will be possible after obtaining the permission of dedicated (paid).
Complete information about the service the mobile terminals and receiving news, you can find on the corporate website: WWW.infotvfm.pl .
Regards,
Team InfoTVFM"

So it seems to "marketing babble".
They cut costs and switch off unused transmitters.
Warsaw is an exception for foreign visits of engineers, politics and other bussines persons, including investments funds could finance a project and there is a need to show working DVB-H.

The Polish DTT multiplex MUX-1 is now expected to be launched at the end of this year or beginning of 2012 and to be fully up and running in time for next year’s Euro 2012 football championships.
Furthermore, according to Rzeczpospolita, it could include a HD channel from the public broadcaster TVP.

The agreed channel line up of the multiplex is currently TVP’s three main channels TVP1, TVP2 and TVP Info, along with the new stations Eska TV, ATM Rozrywka TV, UTV and Polo TV, the latter having recently taken the place of Kino Polska Nostalgia.

The new channels will launch at different times, with the last to make its debut expected to be ATM Rozrywka TV, and all have to sign an agreement with Emitel, which has secured the licence to operate the multiplex.

Poland’s second and third multiplexes were launched in late 2010 and ASO has been set for the end of July 2013.

Ministry of Infrastructure prepared amendment of regulation about National Frequency Allocation.
Channels 61,62 and 68 will be transfer to DVB-T.
Now, channels 61-69, only 61, 62, 64, 65 and 67 are available for DVB-T.
From amandement channels 61, 62, 64, 65, 67will be available for broadcasting.
Since summer next year only channels 68 and 69 will be not available for DVB-T.
UKE (Polish BnetzA) plans to allocate digital dividend for 61-69.
Now fixed wireless (*-nomadic) telephone operator Sferia uses channel 65 to uplink their CDMA network.
Sferia provide nomadic telephone - You can carry Your own telephone with fixed numbers and use everywhere is signal.
But You can't move (behind one BTS during conection.
You can have a fixed number and use phone everywhere.
ULE plans to allocate other mobile (and "full mobile") services in channels 61-69.
In transient period (for now to 31.07.2013) DVB-T in few localisations wil be use channels 61, 62 and 64 (and maybe 67).
Now, MUX2 use channel E61 from Rzeszów and Rabka, channel E62 from Wisła and will be use channel E64 from Cracow.

One sentece I found in UKE site, but I forgot where.
ASO start in december 2012 (first analogue transmitters switch off).
ASO schedule is under project and if it ready, You may read here.
First MUX1 transmitters will be on air before 15 of december this year.
It will be:
- Jemiołów (E45 SFN witch Wichów)
- Wichów (E45 witch Jemiołów)
- Warszawa Raszyn (E58)
- Wisła Skrzyczne (E62)
- Rzeszów Sucha Góra (E42).
So, first analogue switch off should be expected in those area.
Probably ASO start in Jemiołów, Wichów and Warszawa, may be in this time also in Rzeszów and Wisła.
They could switch off Poznań and Iława, due to high power MUX-3 runs in this sites (MUX3 carying TVP1, TVP2 and TVP Info/regional).
Channel of analogue TVP1 from Wichów on E21shoult be take (as i see somwere in UKE site) to Śnieżne kotły, to run MUX2.
Only Giżycko (north east Poland, close to Kalinigradskaja Obłast') have no free channel to run MUX2
MUX1 have all channels in all sites.

@vari107:
Thank you for the info to Mux-4. Apart from "Czyfrowy Polat"s website there's no information about it, even not on RadioPolska.pl. Proably this Mux is operated by Polsat, not by EmiTel. Hope that RadioPolska enters this Mux in it's lists next time.
With the other 18 FTA's they mean the other 3 muxes.
I wonder why the want to start "mobile TV" again (or do they mean "portable"?). DVB-H has failed some years ago: Too less compatible mobiles when started. And later the smartphones could receive DVB-T. The differences of Mux-4 are the regular DVB-T standard and the video resolution, DVB-H had about 320x200 pixels, this was for mobiles only.
Dou you have the transmission parameters (MBit/s, GI, FEC etc.) for Mux-4?

This multiplex contains both standard and low resolution tv channels for tv sets and mobile phones/tablets or other android devices. This was done in that way, because UKE (office of electronic communication) wanted to use these frequencies for mobile television.

The operator uses it to visually make channel list longer.

First three mux-es are transmitted in Horizontal polarisation, but this one is in Vertical. It doesn't make any special diffrece if the signal is very strong, and helps with mobile reception.
